[PATCH V6, 0/5] Support multi-hardware jpeg encoding using of_platform_populate

[kyrie.wu]

This series adds support for multi hardware jpeg encoding, by first
adding use of_platform_populate to manage each hardware information:
interrupt, clock, register bases and power. Secondly add encoding 
work queue to deal with the encoding requestsof multi-hardware
at the same time. Lastly, add output picture reorder function
interface to eliminate the out of order images.

This series has been tested with both MT8195.
Encoding worked for this chip.

Patches 1~2 use of_platform_populate to replace component framework
to manage multi-hardware.

Patch 3 add jpeg encoding timeout function to judge hardware timeout.

Patch 4 add encoding work queue to deal with multi-hardware encoding
at the same time.

Patch 5 add output picture reorder function to order images.

Changes compared with v5:
- use of_platform_populate to replace component framework to
manage multi-hardware in patch 2.

Changes compared with v4:
--No change compaered with v4

Changes compared with v3:
--Structure patches for consistency, non-backward
  compatible and do not break any existing functionality

Changes compared with v2:
--Split the last two patches into several patches
  to enhance readability
--Correct some syntax errors
--Explain why the component framework is used

Changes compared with v1:
--Add jpeg encoder dt-bindings for MT8195
--Use component framework to manage jpegenc HW
--Add jpegenc output pic reorder function interface
